The racist hatemonger, 24, wrote a blog post about the encounter, in which he shoved the woman and repeatedly shouted, "leftist scum." The Daily News earlier identified Heimbach from video of the incident.

"[Video] features yours truly helping the crowd drive out one of the women who had been pushing, shoving, barking, and screaming at the attendees for the better part of an hour," he wrote in a post on the website for the Traditionalist Youth Network, a group that promotes white supremacy.

Heimbach — who did not immediately respond to calls and emails for comment — blamed the tense situation on Black Lives Matter protesters, stating that the group is a "general purpose angry mob" focusing on "anti-white" matters. The Black Lives Matter demonstrators were causing all the problems, cursing at attendees and screaming threats, Heimbach says.

"There were no racial epithets or racial provocations from either the rest of the audience or from our group. There was nothing racial about the event until BLM stormed in and made it racial," he wrote. "They crashed the party, as they've crashed numerous previous ones and will crash the next one."

Attendees have said otherwise. University of Louisville student Shiya Nwanguma said she was called "a n----r and a c--t," she told a local reporter.

One protester, 17-year-old Henry Brousseau told the Courier-Journal that he had filed a report with the Louisville police against a woman in Heimbach's group who allegedly assaulted him.

Another demonstrator, Molly Shah, watched as Heimbach tried to recruit other attendees to his cause.

"I watched him for hours recruit Trump supporters with five of his buddies," said Shah. "They later attacked the group I was with. The Neo-Nazis threw punches and kicked us. I am still awake now because my body is sore."

The groups responded back and forth with chants, attempting to drown each other out, Heimbach wrote.

"Honestly, I had planned to merely attend as an idle spectator, but the protesters were as hostile as anything I've seen at actual nationalist events. They've actually convinced themselves that these rank-and-file Trump supporters and even Trump himself are synonymous with the [Ku Klux] Klan, or at least with outright nationalists like myself," he wrote.

Heimbach — who wore a red "Make America Great Again" hat to the rally — said he will avoid additional Trump events "to ensure that I don't become a distraction."

"White Americans are getting fed up and they're learning that they must either push back or be pushed down," he wrote.

Heimbach has exposed his hateful viewpoints in various interviews, stating that he isn't a supremacist — "I simply believe my people deserve a voice," he told ABC affiliate WRTV last week, after being fired three weeks into his job with the Indiana Department of Child Services. He previously garnered headlines for starting a White Student Union, an off-campus organization, while he attended Towson University. Heimbach has also been banned from entering the United Kingdom due to his racist views.

People online were quick to discredit Heimbach's account of Tuesday's incident.
